Two things were needed to get this test passing.

1. The test removed iframes from the DOM around when they had attempted navigations
in other processes, and then we received IPC about a frame that didn't exist any more.
This is fine.  I removed the assertions.  If the frame is gone there's nothing to do.

2. The test verified that Document::canNavigate checks were in place.  I needed to
make that function take a Frame instead of a LocalFrame and everything tested in that
wpt test passed.
